Lead networks utilizing a saturable core memory

AUTOMATIC feedback control systems have been deeply explored and widely discussed throughout the literature. This paper will discuss special circuits which are peculiarly adaptable to such systems. In particular, if the system is of the type employing a modulated carrier signal, it is possible to nullify completely the effect of a simple time lag by inserting nonlinear circuit configurations which are presented here. The circuits are uniformly effective over a wide range of magnitudes of modulation. They are particularly useful since very little power is lost in the network and low impedance loads will not disturb their operation.
